The Nazis had very little support in 1929 but by 1931 it was around 33%. When people felt OK about life, they wanted nothing to do with such a party. The KPD (communist party) also increased their vote significantly in 1931 as anger rose. Germans felt they were blamed almost completely for WW1 and were been asked to pay for it. The lost quite large bits of their country such as the Rhineland (equivalent of losing Kent and Sussex for the UK) as well as all their overseas colonies (most given to the UK). As we know once they got power, only one voice was heard and it was everywhere. They misused patriotism horribly and they were desperate to find bogeymen to blame for their perceived problems (Jews, Capitalists, Communists, People who didn't fit in, Slavs). If a lot of people resisted in Germany, the Nazis often quickly backed down, which might surprise some people. Their ideal was a German small farmer who worked his own small farm and his family had for over a 1000 years. A person who made a living through hard physical toil. The bedrock of their support came from small town Germany and areas threatened by another country like East Prussia. Lots of opportunists jumped on the bad wagon in 1933, then silently mingled in with everyone else in May 1945 and lived a life of silence about life before 1945.
Some elements of the Nazis can be seen with Trump - over the top Nationalism (how many flags does he have in the background when he talks) demonising other groups very readily (such as immigrants and even Afro-Americans). He seems to deliberately want to make people feel insecure, so he can say he can sort out their concerns which is a tool taken from the Nazis. George Orwell identified in his book 1984, how dictators love creating enemies, people for others to hate. Myself I still think Trump is quite a way off Hitler. Trump is not nearly as militaristic as Hitler. If anything Trump has pulled the USA out of military fights. There is quite a bit of playing to the audience with Trump to get a vote. A deep racism in some parts of the USA has been a major issue since its inception.
